IVEACHINE FCR COVERING INNERSOLES OF THE, GEM TYPE.

Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed January 6, 1915. Serial N o. 864.

To all whom itmay concern ,1 Be it known that I, BICKNELL HALL, a citizen of, the United States, residing in Taunton, in the county of Bristol and State of lVIassachusetts,have invented an Improvement in Machines for Covering Innersoles of the Gem Type, of which the following description, in connection with the accompanyingdrawings, is a specification, like characters on the drawings'representing like parts. This invention relates to a machine for pressing'together layers of fibrous material, and is especially designed and adapted for use. as a finishing machine for inner soles of the. Gem type, which have had a canvas or other fibrous layer previously applied by hand or by the so-called Gem machine to a leather or other inner sole.

The invention has for its obj ectlto provide a machine with which the canvas layer is pressed into the angle'formed by the lip and feather ofthe inner sole so as to produce a smoother and more finished inner sole.

The invention also-has for its object to provide a machine in which the working tools are directly and positively driven, and in which they may be changed substantially in an instant, as will be described.

The invention further has for its object to provide a machine in which the lip may be supported on its outer side and prevented from being distorted o-r'bent outwardly by the canvas as thelatteris pressed into the angleformed by the lip and feather, as will be described. n

Provision is made for limiting the forward movement of the lip supporting tool so as to avoid the canvas covering the lip from being held against movement under the infiuence of the pressing-in tool,-as will be described i These and other features of the invention will be pointed out in the claims at the end of this specification. V

Figure 1 is a vertical section with parts in elevation of one form of machine embodying'this invention. Fig. 2, an enlarged detail in section to show the operating tools. Fig. 3, a side elevation of the machine shown in Fig. 1 with partsin section,"andFig. i, a

detail in section taken on the line 4-4, Fig. 1. Fig. 5, a plan of the gearingbetween the inside and outsidetools, andFig. 6, a detail to illustrate the lateral adjustment of the having a lip f, by hand or by the so-called;

Gem machine, and such as now commonly used in the manufacture of welted boots and shoesv and is further provided with a backing toolor member 6 for supporting the lip f, as will be described.

The toola is designed to work on the inner side of the lip f and is suitably shaped to press thecanvas into the angle formed by the inner surface of the lip andthe upper surface of the inner sole. i

The tool 0 acts upon the canvas to press the same into the angle formed by the outer surface of the lip and the upper surface of the feather or body portion of the inner sole which'is outside of the lip. These tools a, c, are positively driven or rotated and act as feed rolls to. feed the inner sole.

The tool 6 acts as an abutment, guide or backing member to limit the outward movement of the upper or free end of the lip and prevents the lip being moved outwardly beyond a predetermined position or angle with relation to the inner sole, which may be caused by the pressing-in tool 0, drawing the canvas over the lip.

The tool Z) is made as a disk or wheel and is loosely mounted to be turned freely by the lipzas the inner sole is fed forward by the feed tools a, 0.

The tools I), c, are independently movable toward and from the lip f and the tool In the present instance, I have illustrated one construction of mechanism by which the independent movements of the tools I), c,are obtained. To'this end, the tools I), c, are provided with separate, carriers, that for the tool b being shownas a plate 10 provided on its under side with a stud 12, on which the tool Z) is loosely mounted, and having an arm 13 against which abuts a stud or rod 14 which is slidably mounted in a tube or sleeve 15, forming part of the carrier for the tool 0, as will be described. The rod 14 'is engaged by a spring 16,-1ocated within the'tube '15 i and whose tension or strength can be adusted by a screw 17, in threaded engage j ment with the end wall of a hollow boss 18,

which forms a bearing for the outer end of the tube 15, and constitutes a part of the framework of the machine, i

The tool 7) is shown as a disk having a beveled circumference, and it rests upon the tool 0, which is shown as a diskhaving a thin circumferential edge and a beveled or inclined under surface, from the'center of which projects a stud 20, which extends into a socket 21 in the upperend of a spindle or shaft section 22, and .is removably secured thereto by a pin 23, which is straddled by the end ofthe stud 20, which latter is slotted for this purpose in a manner well understood,

, V enthe framework of the machinein a di- 'rection substantially at right angles to that in which the block 25 slides. Theblock 25 has a transverse slot 125', see dotted'lines Fig. 4, in its rear wall, intoivhich is 'ex' tended the-tubeoi sleeve l5,'. .whi ch is mounted to slide inthe hollow boss 18 and in an upright 27 which latter forms part of the framework of the machine. The tube 15 is provided with screw threads28, which are engaged by a nut 29, between which and the hollow boss 18 is interposed a spring. 30, which serves to move the carrler for the tool'c forward'into itsoperative position,

' whilethe spring 16 serves to move the car'- .rier for the tool b'forward into its operative position. v It will thus be seen that the tools 6, care independently movable toward the work by the springs 16, 30, whose tension or strength can be regulated by the set screw 17 and nut 29.

Provision is made for moving the carriers (for the tools I), c, backward, and for this purpose an elbo\vlever 32 is pivoted to the framework- 33, and has an. arm 34 connected by a l nk or rod35 with a foot treadle (not sh'own),'and has a second arm 36 extended into a slot37'in the block 25 and engaged ,with a cross =pin 38, 'so'that 'by depressing .thefoot treadle (not shown) the elbow lever is turned so as to cause its arm 36 to force the block 25'backward, which carrles with it the'carrier for the tool, I), as soon asavertical'wall 39- on theblock or frame 25 ,en-

gages'the arin 13 on the plate 105 T-heforwardmovement of the carrier for the tool 0 iis'jrlirnite'dvby a'setfscrew'w, with which the arm 3-il of'the elbow lever 32 engages, and the forward movement of the carrier for the tool b is limited, as will be described.

The plate 10. of thecarri'er for the tool I) is mounted to slide in a block 41, which is 7 provided at its rear side w1th a transverse slot 410, see Fig. 2, into which extends a stud or pin L12 affixed to the plate 10 and which engages the front wall of the slot 410 to limit the forward movement of the plate 10 and the tool .7) carried thereby. The

block 26 upon which the carrier block 25 rests, is capableof being moved laterally or substantially at right angles to the path in which thecarrier for the tool 0 is moved, andfor thispurpose, a threaded rod 512 is extended. through a threaded, hole in the block 26 and mounted to turn in uprights 43 of the framework, and is restrained. from longitudinal movement by a pin ll, extended into an annular groove 45 in said rod. The block 26 is provided with side pieces-l6 between which the block 25 is located. (This lateralmovement of the block 25 is permitted by the transverse slot 125 and by the slot 126 which latter is wider than the diameter of the rod 1a as indicated in Fig. a.) Provision is also made for moving the block 41 laterally, and for this purpose, a threaded rod 48 is extended through athreaded hole in the block 41, and is mounted to turn in the uprights a3, but is restrained from lon gitudinal movement by a pin 49 extended into an annular groove 50 in said rod. The

- lateral movement of the block ll is permitted by the arm 13 being disconnected from the rod 1-1. In this manner, the tools 6, 0, can be moved laterally with relation to the tool a in opposite directions after the manner represented in Fig. 6.

Provisionis made for positively or directly driving the tool 0, and yetallow for the bodily'movement of the same. T 0 this end, the shaft section 22 is provided on its under surface with a tongue 52, which fits into a slot formed in the upper surface of a second shaft section 53, which in turn is provided on its under surface with a slot, not shown, but which runs at right angles tothe tongue 52, and this latter slot receives a tongue 5%,projecting from the upper surface of a third shaft section 55, which is journaled in bearings 5G, 5? in the framework, and has secured to it a bevel gear 58, which meshes with a bevel pinion 59 on a main or driving shaft 60, provided with the usual fast and loose pulleys 61, G2.

The shaft sections 22-, 53, 55, are connected together by pins 63, '64, so that the three sections may be rotated as one piece and be longitudinally movable as one piece, and

,said pins are extended through elongated slots, only one .65 of which is shown in Fig. 1,, so as to permit the shaft sect ons 22, to'b'e moved laterally with relation to the section to provide for the movements of the tool 0 above described. :v

The shaft sections 2 2, '53, 55, may be moved longitudinally in a downward direction, by a lever 7 O, seeFig. 3, and may be moved'upwardly by a spring71. stance the bevel gear 58 is providedin its bore with substantially diametrically opposite slots 72-, see Fig. 3, into whichextend the'ends of a pin73 carried by'theshaftsection 55, and a gear 7 1 is secured to the shaft section 55 to rotate therewithby a pin 75. Thetool a is'detachably secured to a rotatable shaft, composed of twosections 7'6, 77, which are joined together by uni versal joint or coupling-composed of members 78, 79, which are arranged so uslltopermitthe tool carrying Section 76 to be moved so as to adjust the tool'a toward and from the tools I), c. The shaft section 76 is mounted to turn in a bearing hub 80, pivotally mounted in the framework and forming part ofra lever 81, whichis capable of being turned on its pivots by adjusting set screws 82, 182, provided with lock nuts 83,

84. Rotation is imparted to the shaft section 76 by the upper shaft section 77 through the coupling 78, 79, and the shaft section 77 is driven from the main shaft by the gears 59, 58, 74, which latter meshes with a large gear 86, which meshes witha pinion 87 on a shaft 88, see Figs/3 and 5, which shaft has a large gear 89, which meshes with a gear 90, secured tothe shaft'section 77 to rotate therewith and to permit the shaftsec tion to be moved longitudinally, when it is desired to adjust the tool 66 toward andfroin a support 91 for the inner sole.

The shaft section 77has its 'upper end threaded tobe engaged by an adjusting nut 92 and a lock nut 93, and is engaged with the gear 90 by a pin 94, which extends into diametrically opposite slots 95 inthe-hub of the gear 90. The shaft I section 77 is forced downwardly by a helical spring 96 which encircles it within the hub of the gear 90. The work support 91 is shown as'a disk fast on a spindle 97 which is extended into an elongated hub 98, having-"a bearing in the framework 33 and provided with a gear 99, which meshes with and is driven by the gear-74. I i The hub 98 is provided at its upper end with substantially diametrical slots 100, into which project the ends of a pin 101, carried by thespindle 97, which is encircled within the hubby a helical spring 102, which serves to yieldingly support the work supporting table or disk 91, and whose tension is regulated by a nut 103, having a threaded hub 10 i whichengages the threaded lower end of the hub 98. The threadedhub 1045 is locked in its adjusted positionby the nut '105. The upward movement of the-work support 91 is limited by a nut 106 .on the spindle 97"en- In the present ingagingb'the nut-103, and the spindle 97 is provided with a link or swivel 108, by which the spindle 97 may be connected with a foot treadlefnot shown) so that,'the work support 9l can be lowered. The work table or disk'91 is held up into itsoperative position by the spring102, and the upward movement of the'table under the influence of said springis limited by the nut 106 on the spin dl e 97- engaging the nut 103. Through the pin and slot connection 101, 100, the spindle 97 is rotated with the hub98.

The spindle 97 and the link 35 may be con-- nected with separate foot treadles, or they may be connected with'one, so that, when the treadle isdepressed, the work table 91 is lowered substantially at the same time the toolsb, 0, are moved backward and with these parts in the position just described, the covered inner sole may be placed on the table-in position to beengaged on the inner side of the lip by the tool a, when the pressure is removed from the foot treadle and the table is elevated into its working position. Then the table is in its working position, the operator manipulates the inner sole, sothat the inner surface of the covered inner sole is engaged with the tool a, before the tools 6, c, are engaged with the outer surface of the covered lip. The machine is then set in motion,and the tools a, c, are

rotated to feedthe covered inner sole, which is guided by the operator. The tools a, c, not only press the gummed covering down 0n the body of the inner sole and 011 the feather but also press the covering against thB'OPPOSltG sides of the lip f at thebase of .the same, and the tool a forces the canvas covering into the angle formed by the inner side of the lip with the inner sole, and the tool'c presses'the canvas covering into the angle formed "by the outside of the lip with the feather of the inner sole, and the tools a, Z), are so constructed or arranged asto permit the canvas covering the lip to be moved over thelip. 7 by the pressing-in tool 0, which draws the more or less loose material envelopin g the lip over the upper edge of the lip, which latter is prevented from being moved outwardly or later-ally with relation'to the tool a and thereby distorted, by

meansiof the tool 6, which is employed as an abutment or backing member to support the upper portion of the lip on its outerside.

By reference to Fig.2, it'will be seen that the tool a is so shaped as not to engage the upper'portion of the lip, and consequently the covering'thereon is'free to respond to the pressing-in action of the tool 0 which draws the surplus canvasover the lip and past the backing tool 6 without distortion of the, lip. To facilitate movement of the canvas covering over the lip, the tool I) may and preferablyiwill have its lower portion .150 made ofsinaller diameter sofasto reduceithe frictional contact between thew-tool b and the canvas covering on the outside of the lip. In this manner the somewhat loose material enveloping the lip is caused to adherejto it firmly and smoothlyand at the same time, thev portions of the canvas cemented to the inner sole on opposite sidesof the lip are still further pressed into firm engagement with the inner sole and a more finished inner sole of the-Gem type is thus produced; v V V It will be observed that the tools a,- 0,

I 'arespositively or directly driven, without apparatusembodying thisinv'ention, but it r interfering with the bodily movement of the same.
